'summary-focused' originates from the English word 'summary' combined with 'focused', where 'summary' meant 'a brief statement or account of the main points of something' and 'focused' meant 'concentrated on a particular point or task'.

'summary' changed from the Latin word 'summarium' and 'focused' from the Latin word 'focus', eventually becoming the modern English word 'summary-focused'.

Initially, 'summary' meant 'a brief account', and 'focused' meant 'concentrated', evolving into the current meaning of 'concentrated on providing a concise overview'.
